FLOOR AND CEILING PLATE.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed. March 5, 1908. Serial No. 419,389.

To all whom it may concern:

I Be it known that I, ALBERT R. VVELLs, a citizen of the United States, residing at Southington, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Floor and Ceiling Plates and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this speci- 'l'ioation, and represent, in

Figure 1 a perspective view of a floor and ceiling plate constructed in accordance with myinvention, and shown as applied to a floor. Fig. 2 an inside plan view of the same. Fig. 3 a sectional view 011 the line ab of Fig. 2. Fig. 4 a broken inside plan view of the hinged ends of the members.

This invention relates to an. improvement in floor and ceiling plates for steam and other pipes, the object of the invention being a construction specially designed for a ceiling plate as it includes means for holding the plate securely upon the pipe, but it is also well adapted for floor plates as the parts are not liable to accidental displacement; and the invention consists in the construction hereinafter described and particularly recited in the claims.

As in the usual construction of floor and ceiling plates my improved device is made in two parts 2 and 3 substantially semi-circular and each formed with central flanges 4 and 5 the ends of the flange 5 terminating in hooks 6 and 7. One plate as 3 is formed with a stu d or postS and the other member 2 with a lip 9 having a perforation 10 adapting it to be set over the post 8. At the opposite ends one member is formed with a lug 11 and the other with a locking eye 12 adapted to engage therewith for locking the plates together. Engaged with the flange 5 is a spring 13 following the inner wall of the flange and having its ends 14 and 15 bent inward beneath the hooks 6 and 7. These spring ends bear against the pipe when the members of the plate are interlocked so as to firmly hold the plate in position. To pre vent the displacement of the parts the lip 9 is formed with a beveled edge 16 which rides beneath the edge of the spring 13 as clearly shown in Figs. 2 and 3 of the drawings. This edge 16 will remain in engagement with the edge of the spring until the members are widely separated and hence the ends of the plates opposite the latching device will not become disengaged and are therefore not necessarily riveted together.

I claim:

A floor and ceiling plate comprising two parts each formed with a semi-circular flange, the flange of one member formed with hooks, a spring engaged with said flange and having its ends passed beneath said hooks, the ends of the members overlapped and one member formed with a post and the other with a perforated lip adapted to engage therewith, the opposite ends of the members adapted. to be interlocked, the said lip formed with a, beveled edge adapted to extend beneath the said spring, substantially as described.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
